As you read the epistles of Paul, toward the end he tends to describe what is it that you must do. For specific opportunities to do charitable work, send your resume to your local diocese and they'll match you up with something. Yes, you can hire help.
"Yes, you can hire help."

I think you see now why works buy you nothing.
